One embodiment of the present invention may provide a vehicle wheel bearing which rotatably mounts and supports a wheel of a vehicle on a vehicle body. The vehicle wheel bearing, according to one embodiment of the present invention, may comprise: a rotating element that rotates along with a wheel of a vehicle; a non-rotating element that is mounted and fixed to a vehicle body; a plurality of rolling elements interposed between the rotating element and non-rotating element; and a sealing member mounted between the rotating element and non-rotating element to prevent foreign substances from being introduced thereto. According to one embodiment of the present invention, the sealing member may comprise: a first member mounted on one of the rotating element and non-rotating element of the wheel bearing; and a second member mounted on the other of the rotating element and non-rotating element of the wheel bearing. According to one embodiment of the present invention, the first member of the sealing member comprises: a press-fitting part; and a flange part extending from the press-fitting part in a radial direction. According to one embodiment of the present invention, the second member of the sealing member may comprise: a press-fitting part; a flange part extending from the press-fitting part in the radial direction; and an axial extension part extending from the flange part in an axial direction and disposed to face the press-fitting part of the first member. According to one embodiment of the present invention, the axial extension part may have a groove having a structure recessed in the radial direction and extending in a circumferential direction.

    Un mode de réalisation de la présente invention peut fournir un roulement de roue de véhicule qui monte et supporte de manière rotative une roue d'un véhicule sur une carrosserie de véhicule. Le roulement de roue de véhicule, selon un mode de réalisation de la présente invention, peut comprendre : un élément rotatif qui tourne conjointement avec les roues d'un véhicule ; un élément non rotatif qui est monté de manière fixe sur une carrosserie de véhicule ; une pluralité d'éléments de roulement interposés entre l'élément rotatif et l'élément non rotatif ; et un élément d'étanchéité monté entre l'élément rotatif et l'élément non rotatif pour empêcher des substances étrangères de s'écouler à l'intérieur de ceux-ci. Selon un mode de réalisation de la présente invention, l'élément d'étanchéité peut comprendre : un premier élément monté sur l'un de l'élément rotatif et de l'élément non rotatif du roulement de roue ; et un second élément monté sur l'autre de l'élément rotatif et de l'élément non rotatif du roulement de roue. Selon un mode de réalisation de la présente invention, le premier élément de l'élément d'étanchéité comprend : une partie d'ajustement par pression ; et une partie de bride s'étendant à partir de la partie d'ajustement par pression dans un sens radial. Selon un mode de réalisation de la présente invention, le second élément de l'élément d'étanchéité peut comprendre : une partie d'ajustement par pression ; une partie bride s'étendant à partir de la partie d'ajustement par pression dans le sens radial ; et une partie d'extension axiale s'étendant à partir de la partie de bride dans un sens axial et disposée pour faire face à la partie d'ajustement par pression du premier élément. Selon un mode de réalisation de la présente invention, la partie d'extension axiale peut avoir une rainure possédant une structure évidée dans le sens radial et s'étendant dans un sens circonférentiel.

    본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 차량용 휠베어링이 제공될 수 있다. 본 발명의 일 실시예에 따른 차량용 휠베어링은 차량의 휠과 함께 회전하는 회전요소와; 차체에 장착되어 고정되는 비회전요소와; 회전요소와 비회전요소 사이에 개재되는 복수의 전동체와; 회전요소와 비회전요소 사이에 장착되어 외부 이물질의 유입을 방지하는 씰링부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재는 휠베어링의 회전요소와 비회전요소 중 어느 하나에 장착되는 제1 부재와; 휠베어링의 회전요소와 비회전요소 중 다른 하나에 장착되는 제2 부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재의 제1 부재는 압입부와; 압입부로부터 반경방향으로 연장하는 플랜지부;를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재의 제2 부재는 압입부와; 압입부로부터 반경방향으로 연장하는 플랜지부와; 플랜지부로부터 축방향으로 연장하여 형성되며 제1 부재의 압입부와 대향하여 배치되는 축방향 연장부;를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 축방향 연장부에는 반경방향으로 함몰된 구조를 가지며 원주방향을 따라 연장하여 형성되는 홈이 구비될 수 있다.
